gerbyx

Gerber parser that generates Shapely objects for PCB and geometries

• PyPI package: https://pypi.org/project/gerbyx/
• Free software: MIT License

Features

• ✅ Gerber X2 & X3 Support: Full support for both Gerber X2 and X3 standards
• ✅ Shapely Geometry Generation: Converts Gerber commands to Shapely objects
• ✅ Macro Apertures: Supports custom aperture macros (AM)
• ✅ Aperture Blocks: Handles aperture blocks (AB) with full instantiation support
• ✅ Layer Polarity: Dark and Clear polarity for additive/subtractive operations
• ✅ Attributes: File, aperture, and component attributes (TF, TA, TO)
• ✅ X3 Component Attributes: TO.C (reference), TO.CVal (value), and more
• ✅ Delete Attributes: TD command for removing attributes (X3)
• ✅ X3 Validation: Built-in validator for X3 compliance
• ✅ Visualization: Built-in Matplotlib visualization
• ✅ CLI Tool: Command-line interface for quick processing
• ✅ Performance Optimized: +6% faster with zero overhead logging
• ✅ Secure: No eval() vulnerabilities, safe expression evaluator
• ✅ Logging System: DEBUG/INFO/WARNING/ERROR levels with lazy evaluation

Gerber X3 Features

• Component reference designators (TO.C)
• Component values (TO.CVal)
• Inline comments with #
• Explicit macro closing with %AM*%
• Mandatory M02 end-of-file marker
• Aperture blocks instantiation
• Delete attributes (TD)
• X3 validation with error reporting

🚀 Quick Start

from gerbyx import logger
from gerbyx.tokenizer import tokenize_gerber
from gerbyx.parser import GerberParser
from gerbyx.processor import GerberProcessor

# Optional: Enable debug logging
logger.set_level('DEBUG')  # or 'INFO' (default), 'WARNING', 'ERROR'

# Parse Gerber file
with open('file.gbr', 'r') as f:
    gerber_source = f.read()

processor = GerberProcessor()
parser = GerberParser(processor)
tokens = tokenize_gerber(gerber_source)
parser.parse(tokens)

# Get geometries
geometries = processor.geometries
print(f"Generated {len(geometries)} geometries")

🔒 Security

From Version 0.2.0 critical security fixes are included:

• ✅ Removed eval() vulnerability (RCE risk eliminated)
• ✅ Safe expression evaluator for macro expressions
• ✅ Input validation and sanitization

See docs/SECURITY.md for details.

⚡ Performance

Optimized for speed:

• Parsing: +22% faster
• Tokenization: +13% faster
• Small files: +36% faster
• Zero overhead logging

See docs/OPTIMIZATION_SUMMARY.md for benchmarks.
